    The geomagnetic storm conditions of 8/30 and 8/31 have passed, but not before setting some impressive aurora what were seen as far south as MN and WI.

      MN and WI.

      Sunspot region 663 managed to get off an M1.4 flare on the 31st.
      While the resulting CME wasn't squarely Earth-directed, we should take
      a glancing blow from it on or about the 3rd. That could touch off
      some active geomagnetic conditions. Old sunspot region 649 has come
      back into view. Back in July, it was responsible for some significant
      activity. It appears to be much smaller now than it did then, and is
      only about 1/20th of it's former size. At the present time, that is
      the only sunspot region visible.

      The current solar and geomagnetic conditions are :

      NOAA sunspot number : 25
      SFI : 94
      A index : 8
      K index : 1

      Solar wind speed : 428.4 km/sec
      Solar wind density : 1.3 protons/cc
      Solar wind pressure : 0.4 nPa

      IMF : 4.1 nT
      IMF Orientation : 1.7 nT North

      GOES-12 Background X-ray Flux level : B1

      Conditions for the last 24 hours :
      No space weather storms were observed for the past 24 hours.

      Forecast for the next 24 hours :
      No space weather storms are expected for the next 24 hours.

      Solar activity forecast :
      Solar activity is expected to be very low to low.

      Geomagnetic activity forecast :
      The geomagnetic field is expected to be quiet to unsettled. Isolated
      periods of active levels are possible on 03 September due to a CME
      observed on 31 August.

      Recent significant solar flare activity :
